UNITED STATES PATENT OFFICE.

WILLIAM E. SHEENE, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE NATIONALASPHALT BURIAL VAULT COMPANY, OF BALTIMORE, MARYLAND, A CORPORA' TION.

ASPHALT-MASTIC AND COAL-TAR-MASTIC CASKET VAULT.

No Drawing.

To all 207mm it may concern Be itknown that I. WILLL-nr E. SHEENL,citizen of the United States, residing at Baltimore, and State ofMarylanch'have invented certain new and useful Improvements inAsphalt-Mastic and Coal-Tar- )lastic Casket Vaults, of which thefollowing is a specification.

This invention is a burial container of the type designed to receive.house and protect a coflin or casket which is to be placed in a graveand thus buried in the earth.

The prime object of the present invention is to provide such a burialcontainer as will be proof against seepage, and will efi'ectuallyexclude air. water. dampness and any and all destroying agents to whichburial containers are subject when buried in the earth.

The container of the present invention is molded from a bituminousmastic (an asphaltic mastic or a coal tar mastic) and I have determinedby actual and satisfactory tests that a container made from a bitumi-"nous mastic and buried in the earth or submerged in water will possessthe above mentioned desirable characteristics, and in addition theretothe mastic can be readily and inexpensively produced and containersmolded therefrom in a satisfactory and in-.

expensive manner.

In carrying out my invention. I first produce the bituminous masticwhich preferably comprises bitumen (asphalt or coal tar b v-products).limestone dust. fuller's earth, infusorial earth. and ,it also comprisessand or grits which form a body or filler thereof.

In some instances it is found advisable to add to the above ingredientsa material known as asphalt flux. This gives the mate rials when mixed ahigher degree of elliciency.

In preparing the composition, I prefer to use the ingredients in aboutthe following proportionsviz. approximately sixteen (16) per cent ofbitumen, thirty-four (34) per cent of limestone dust. fullers earth, orinfusorial earth. and fifty per cent of sand or grits, it beingunderstood, of course, that good results can also be obtainedApplication filed November 19, 1921. Serial No. 516,312.

by varying the materials in other proportions. and also to the abovenamed ingredients there can be added five (5) to seven (7) per cent ofasphalt flux, which will increase the efliciency of the composition whenmixed.

'hen using the limestone dust it is not necessary to use fullers earthor infusorial earth. and vice versa.

All of the ingredients as stated above are mixed together and cookeduntil said mixed ingredients reach a paste or mortar consistency such aswill be capable of being poured into moulds. It is first. cooked at atemperature of about 450 Fahrenheit for approximately four (4) hours.and stirred constantly either by hand or machine. It is then poured intomoulds or forms, and when chilled or cooled to a certain degree itassumes the configuration of the moulds or forms, after which time themoulds or forms can be removed.

It is to be understood that the lid for this receptacle is made of thesame ingredients, only poured into a different kind of mould, and thelid is sealed to the receptacle by a composition of the sameingredients. cooked in the same manner, with the exception of adding thesand or grits.

The burial container of the present inven tion is relatively light inweight as compared with containers made of stone or con crete, and isalso fireproof and waterproof. and in fact possesses in a high degreeall of the desired properties necessary to a burial container forprotecting caskets or cofiins when buried in the earth.

\Vhat I claim as new is:

1. A burial container comprising a molded casing formed from abituminous mastic including limestone. sand and bitumen.

2. A burial container comprising a molded casing formed from abituminous mastic including 16 per cent of asphalt, 34 per cent oflimestone and 50 per cent of sand.

In testimony whereof I hereunto aifix my signature.

WILLIAM E. SHEENE.
